Stone Mastic Asphalt (SMA) is a high strength material that produces a surface that in many instances out-performs that of traditional Hot Rolled Asphalt (and pre-coated chippings where required).

These materials are particularly suited to sites of high stress, such as lorry parks, industrial areas, Motorways, Trunk Roads etc. They provide a reduction in surface noise through inverted texture, and often provide benefits during the laying process, as there is less laying equipment required and can generally be trafficked earlier than conventional asphalt without the risk of premature surface failure.

6mm SMA is particularly suited to residential driveways and car parks where it is more resistant to the scuffing action of vehicles turning in confined spaces.
